分析了一个由三质点和弹簧构成的系统的运动问题，给出了三质点质量满足不同关系时各质点的运动微分方程，求出了运动微分方程的解析解，并由此讨论了各质点的运动规律。

The strength of coal and rock mass can be weakened through deep hole relieving shot, so the ability of energy accumulation is reduced, and a large amount of elastic energy accumulated in coal and rock mass is released, which makes it sure that the elastic energy accumulated in coal and rock mass do not exceed the minimum energy induced rock burst. Simultaneously, electromagnetic emission is used to check out the effect of eliminating or reducing the danger of rock bursts.

The spectral curve vs invariant mass is becoming wider and the peak is shifted towards the high invariant mass region with the increase of temperature. However, in ultra high temperature or density envi- ronment, the peak is shifted towards lower region and the curve is changed narrower with the increase of temperature. In the invariant mass region M 憕.-?0.4 GeV?.6 Ge1~, the spectral function is enhanced very much. which contributes to the interpretation of dilepton enhancement results in relevant experi

结果显示高温高密强子物质环境对其有非常重要的影响：ρ谱函数在温度或密度不太高时谱函数曲线变宽，并且峰朝不变质量高的方向移动；在极端高温或高密情况下谱函数却变窄，并且峰朝不变质量低的方向移动，在不变质量M～0.4-0.6 GeV区间谱函数有比较明显的增强，这有助于解释双轻子产生的相关实验现象。

The subdeacon used the Apostolus, the deacons the Evangelarium , and the presiding celebrant the Sacramentarium, which contained all the prayers of the Mass.

It is inportant to understand the limitations of rock mass classification schemes（Palmstrom and Broch,2006）and that their use does notreplace some of the more elaborate design procedures.However,the use of these design procedures requires access to relatively detailed information on in situ stresses,rock mass properties and planned excavation sequence,none of which may be available at an early stage in the project.As this information becomes available,the use of the rock mass classification schemes should be updated and used in conjunction with site specfic analyses.
